So I installed Prime95, follow their instructions to connect to PrimeNet and as soon it started to test, the computer crashed. I tested once again, opening Prime95 and this time it immediately started a test and once again the computer crashed.
Does this means its a RAM issue?
If I become half a percent smarter each year, I'll be a genius by the time I die
BTW, no need for primenet, when you first start it just select torture test or whatever the option is.
Well, the crashing definitely makes it clear it's not a Sierra issue at least
It is also extremely unlikely to be SSD.
It leaves a few things:
a) Heat
b) Memory
What you can do is re-run the torture test option "Small FFT's" (top option). That tests pretty much no RAM. If it doesn't crash after say 30 minutes, then it's not heat (which is unlikely anyway given the scenario you've described).
That leaves memory.
You said you have 8GB, so probably it's either 2x4GB sticks, or 4x2GB sticks. Try taking all but one stick out of the system and re-run Prime95 "custom" test.
If it works, keep moving things around until you find the bad stick of memory. Then RMA it to the manufacturer, there should be a lifetime memory on it.
Well it could still be memory, but it also could mean a problem with your CPU. Are you sure the heatsink and fan are working properly? It could be heat related.
No install needed, just run the executable. It will show your tjmax temp and your current temps for each core. At idle for an i5 the temps should be around 30 C probably, or less. Watch it closely when you run Prime95 again and see if it spikes. If it does, it indicates the heatsink and fan are not working correctly and need to be re-seated with new thermal paste, or replaced.
I am not sure of your exact model of i5 so not sure what your tjmax is, but RealTemp will report it. You should be at least 20 C under this temp at all times. When the chip hits this temp, it will shutdown to prevent damage.
Leave RealTemp running in the background while you do normal CPU tasks, and report back what your tjmax is and what your min and max temps were, and we can rule out heat.
- it was worth a shot...
